Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed October 10, 1904. Serial No. 227,963.

To all whom it may concern.-

Be it known that I, JOHN W. DAvIs, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Smoothing-Irons; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertai'ns to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to a new and useful improvementin smoothing-irons, especially to the character of irons having a handle portion adapted to be removed when it is necessary to apply the same to a warmer iron.

In the accompanying drawings, forming a part of this specification, I have illustrated my invention by several views, in which Figure 1 is a side elevation of my improved iron, showing the means employed in looking the removable handle portion. Fig. 2 is a top plan view of the same, and Fig. 3 is a bottom view of the handle portion. Fig. A is a transverse section illustrating the connection of the handle and body of the iron.

Numerals of reference designate like parts throughout the several views.

The numeral 1 represents the body portion of the iron, on the top of which and integral with the same are formed the securing-lugs 2 2, the inner face of each lug being undercut on an angle forming a dovetailed socket to receive the handle portion 3. Pivotally seated in a support 4, formed integral with the removable handle portion 3, is a pawl 5, formed on one end of which is a post 6, seating in a helical spring, the upper end of which abuts the under side of one end of pawl 5, the other end being formed into a tapered portion adapted to engage teeth 7, formed in the top of the body portion 1, when said spring is in normal position, and disengaging with said teeth when the spring is compressed by pres-.

sure on post 6, as will be evident. A flat spring 8, secured to the handle portion 3 and having a bearing on the engaging end of the pawl 5, will aid in keeping this member firmly in its seat. The bottom or engaging portion of the handle 3 is formed with a slight taper longitudinally that is wedge-shaped in the direction of its length, as seen in Fig. 8, so as to wedge between the lugs 2 2, the two lugs at one end of the iron being slightly closer together than the opposite pair, so as to receive the narrow part of the handle portion. The under side of the handle portion is provided with the engaging projections 9, four of which engage the lugs 2 and rest upon the top of the iron body, while the remainder simply rest upon the body. This is for the purpose of reducing as much as possible the contact between the body portion and removable handle and also affords an air-space between the two members. By this means of reducing the contacting surfaces of the iron between the two bodies it will tend to keep the handle portion cool.

It is understood that the gripping portion of the handle 3 will be made of wood or any substance that does not retain the heat.

1, which is necessarily detached during the period of heating, the operator simply catches hold of the handle portion 3 and by guiding it between the securing-lugs 2 2 until the pawl 5 becomes seated in the teeth 7 the handle will become firmly attached to said body portion. The longitudinal edges of the projections 9 which engage the lugs 2 are slightly inclined outward to adapt said projections to snugly fit into the dovetailed recesses formed by the lugs 2 2 and preventing the handle from being pulled upward from its seat. The pawl 5 engaging the teeth 7 and being held in position by the spring 8 will prevent the handle from any backward movement. When it becomes necessary to remove this handle portion 1, the operator simply presses down on the end of the pawl 5, thus lifting the engaging end from engagement with the teeth 7, and then slides said handle away from its seat between the securing-lugs 2 2.

Having thus fully shown and described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a smoothing-iron having a removable handle portion, of securing-lugs formed on the top of the body portion, said lugs having their proximate faces undercut, projections depending from the handle portion and having their opposite faces inclined to engage the undercut portions of the lugs, additional projections depending from the handle portion to bear on the body portion, a locking-pawl pivotally secured to the handle portion and arranged to engage teeth formed in the top of the body portion, and a spring bearing against the locking-pawl and handle portion and having an air-space WVhen it is desired to use the body portionto insure normal engagement of said pawl and teeth.

2. Thecombination with a smoothing-iron having a removable handle portion including abase, of securing-lugs formed on the top of the body portion, said lugs having their proximate faces undercut, projections depending from the handle portion and having their opposite faces inclined to engage the undercut portions of the lugs, additional projections depending from the handle portion to bear on the body portion, a locking-pawl pivotally secured to the handle portion and arranged to engage teeth formed in the top of the body portion, and a spring bearing against the locking-pawl to insure normal engagement of said pawl and teeth, the base of the handle portion being longitudinally tapered and the securing-lugs being positioned on the body portion in relative relation to receive the tapered base of the handle portion and maintain it in predetermined position relative to the body portion.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN W. DAVIS.
